Abstract
The present invention broadly comprises a beverage dispenser for filtering and dispensing liquid beverages. The device includes an upper reservoir for receiving a liquid therein and is adapted to releasably secure a filter. The filter is arranged for communication with a lower reservoir for receiving the liquid beverage therein. The lower reservoir includes means for dispensing the filtered liquid and the filtered liquid therein may be heated or cooled by means of heating or cooling devices. The beverage dispenser is compact, portable and housed in an aesthetically appealing canister. Removal of the filter allows other beverages, such as lemonade, or tea, to be stored and dispensed on demand.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/420,651, filed Oct. 23, 2002, which application is incorporated herein by reference.
- The present invention relates generally to an apparatus for dispensing beverages, and more particularly, to a beverage dispenser including a removable filter for filtering tap water, and optionally, chilling means, heater means, and CO2 charging means for dispensing chilled, warmed, ambient and effervescent beverages. The beverage dispenser may be adapted for use with liquids other than water, for example, juices, teas and the like. The beverage dispenser of the present invention is compact, portable and aesthetically appealing.
- Consumers are increasingly concerned with the quality of municipal, rural, and water well drinking water. In direct response to water quality issues, many consumers now demand alternative sources of safe drinking water. Consequently, the market for bottled spring and purified waters has increased significantly. In fact, the demand for specialty drinking waters has increased so dramatically that bottled water is now considered by many to be a basic commodity.
- Bottled water is typically delivered to homes or businesses in portable 5-gallon containers designed to fit on stand-alone floor water cooler units, which are either rented from suppliers or purchased by the consumer. The stand-alone floor units are often large and typically require the consumer to buy bottled water from the supplier on a regular basis, e.g., weekly or monthly depending on the demand for bottled water, which can be costly. Costly bottled water can be substituted with low cost tap water and filtered to obtain water that is as clean, safe and even more pure than bottled drinking water.
- Additionally, when they are filled to capacity, the 5-gallon containers used in association with most water coolers are heavy and often difficult to load onto the water cooler unit. Thus, there exists a need for a beverage dispenser unit that is relatively inexpensive and compact in size, such that it may be conveniently placed on a counter top.
- To maintain bottled water at an ideal temperature for drinking, i.e., 38-43° F., a chilling mechanism that operates continuously and efficiently is required. Typically, refrigeration equipment for such water coolers includes conventional compressor-type mechanical refrigeration systems, which undesirably increase the overall cost complexity, size, and power consumption requirements of the water cooler. Alternatively, thermoelectric heat transfer modules provide a more compact and cost-effective means for chilling water within a cooler reservoir. However, the chilling capacity of thermoelectric modules is relatively small when compared to conventional compressor-type refrigeration systems, as a result thermoelectric modules require a longer chilling time or dependence on the formation of an “ice bank” for immediate chilling following a large withdrawal or several successive withdrawals of water from the water cooler. Thus, there also exists a need for a beverage dispenser unit that provides a chilling mechanism with the size and power consumption advantages of the thermoelectric modules, but which cools water more quickly and efficiently.
- While the demand for bottled water has increased in residential and commercial applications, it has not replaced the convenience of tap water readily available from municipal, rural or private well systems. However, tap water from municipal sources often contains contaminates or chemical residues used in purification processes, e.g., chlorine, that are unhealthy and undesirable. Many private well systems contain suspended solids, organic chemicals and pathogenic bacteria. Thus, there exists a need for a beverage dispenser unit that also provides a high efficiency water purification system for the purification of common tap water from municipal, rural, or private well systems.
- Water cooler units are often prominent fixtures in home and office environments. These units are typically comprised of a rectangular cooling unit that supports a cylindrical water bottle on top. While functional, these water cooler units are plain and lack any artistic design. Thus there exists a need for a beverage dispenser unit that is artistic in design.
- Many variations in water cooler units are known in the art. Typically, these water cooler units are used to dispense cool water from a bottled source. For example, U.S. Pat. No. 6,003,318, entitled, “Thermoelectric Water Cooler,” describes a water cooler comprising a thermoelectric heat transfer module that chills water within a cooler reservoir. The water cooler includes a sensor that detects build-up of an ice bank within the cooler reservoir, and signals a controller to regulate the thermoelectric module to prevent excessive ice bank growth. This water cooler further includes an air filter for filtering air drawn by a fan, which circulates over a heat sink associated with the thermoelectric module. However, the Water cooler described in the '318 patent does not disclose a device for filtering water and is not suitable for purifying and chilling tap water. Hence, consumers are required to purchase bottled water, which can be costly.
- U.S. Pat. No. 5,771,709, “Electric Counter Mounted Beverage Cooler and Dispenser,” describes a beverage cooler and dispenser. However, the '709 patent does not disclose means for filtering water.
- U.S. Pat. No. 5,072,590, “Bottled Water Chilling System,” describes a chilling system for chilling or cooling a supply of water or the like to a selected low temperature suitable for drinking and other uses. The chilling system includes a thermoelectric heat transfer module having a cold side for extracting heat energy from water contained in a reservoir, and a hot side for transferring the extracted heat energy to a circulating heat transfer fluid. The invention described in the '590 patent does not include a filter for removing contaminates from water.
- U.S. Pat. No. 4,913,713, “Versatile Countertop Cooler,” describes a countertop cooler for standard size water bottles. The '713 patent does not disclose means for filtering water.
- U.S. Pat. No. 5,587,089, “Water Purification and Dispensing System,” describes a system for purifying water, washing a container with the purified water, and filling the container with the purified water. The system includes an apparatus comprising a water inlet system, a water purification system, a container washing system, a container filling system, an auxiliary function system, a mineralization system and an ozonating system. However, the apparatus is not adapted for chilling water or dispensing beverages.
- U.S. Pat. No. 6,112,541, “Compact Cooling Apparatus” describes a water filtering and chilling device. However, while this device is capable of both filtering and chilling water, the device is not capable of filtering both chilled and non-chilled water. In addition, the device may only be used in connection with a faucet, or pressurized source of water. Finally, the '541 patent does not disclose whether the device may be adapted for use with beverages other than water.
- Accordingly, there is a long felt need for a compact, aesthetically appealing beverage dispenser that is energy efficient and capable of filtering water and heating or cooling beverages.
- The present invention broadly comprises a device for filtering liquids. The device includes an upper reservoir for receiving a liquid therein and is adapted to releasably secure a filter. The filter is arranged for communication with a lower reservoir, which lower reservoir receives liquid that has passed through the filter. The lower reservoir may be adapted to comprise means for dispensing the filtered liquid to a user or to other reservoirs wherein the filtered liquid may be heated or cooled by means of heating or cooling elements or infused with a CO2 to create an effervescent liquid.
- It is therefore an object of the present invention to provide a filter unit for liquids that is relatively inexpensive and compact in size, such that it may filter liquid fed into a first reservoir.
- It is another object of this invention to provide a beverage cooler unit that provides a cooling mechanism having size and power consumption advantages over conventional cooling devices.
- It is yet another object of this invention to provide a water filter and cooler unit that filters tap water prior to dispensing.
- It is yet another object of the invention to provide a beverage dispenser unit that is artistic in design.
- These and other objects, features and advantages of the present invention will become readily apparent to those having ordinary skill in the art upon a reading of the following detailed description of the invention in view of the drawings and claims.
- The nature and mode of operation of the present invention will now be more fully described in the following detailed description of the invention taken with the accompanying drawing figures, in which:

- It should be appreciated at the outset that, in the detailed description that follows, like reference numbers on different drawing views are intended to identify identical, or functionally similar, structural elements of the invention in the respective views. Additionally, it should be appreciated that the particular embodiments disclosed herein are presented solely for purposes of illustration and are not intended to limit the scope of the present disclosure and claims. It should be further appreciated that the phrase “essentially similar” as used herein relative to the various embodiments of the present invention is intended to refer to the fact that the various embodiments may comprise similar structural elements, including but not limited to: filter assemblies, spigots, lids, reservoirs, etc.
- The present invention generally comprises a beverage dispenser for filtering and dispensing water or other beverages. The invention may be adapted to include, alone or in combination, a filter assembly, a cooling unit for providing cooled beverages, a heating unit for providing heated beverages, a CO2 charging unit for providing effervescent beverages or may be adapted to dispense filtered water at ambient room temperature. The filtering, cooling, heating and CO2 charging units may be conveniently provided in a self-contained, compact, portable canister and the beverage dispenser may also be configured for providing beverages at ambient temperature. The beverage dispenser includes a removable filter unit such that common tap water may be purified, e.g., to meet NSF International standards. The invention may also be used to provide other chilled or heated beverages, such as lemonade, tea or flavored drinks, on demand.
- The beverage dispenser of the present invention may be configured to comprise an upper non-cooled reservoir, a connecting or collecting reservoir, one or more fluid control assemblies (e.g., check valves), one or more filters, a lower chilled reservoir, a lower heated reservoir, a lower CO2 reservoir, one or more dispensing valves (e.g., spigots), and an outer housing and lid.
- Referring now to the Figures, FIGS. 1, 2 and4 illustrate a
beverage dispenser 100 according to the present invention operatively arranged for dispensing chilled beverages. In these figures it is seen thatbeverage dispenser 100 broadly comprises uppernon-chilled reservoir 102,check valve 104, lowerchilled reservoir 106,outer housing 108,lid 110, andspigot 112. - Upper
non-chilled reservoir 102 is designed to contain a quantity of liquid, such as water, substantially at room temperature. Uppernon-chilled reservoir 102 is typically cylindrical in shape and constructed from molded plastic or stainless steel depending on the liquid to be filtered and chilled. Uppernon-chilled reservoir 102 is formed to provide a large cylindrical opening bordered by a lip structure at the top for input of liquid and a relatively narrow cylindrical opening at the bottom for output of liquid throughcheck valve 104 into chilledreservoir 106.Non-chilled reservoir 102 further includes afilter assembly 114, and agasket 115. It should be appreciated by those having ordinary skill in the art that while a substantially cylindrically shaped beverage dispenser, and associated components are disclosed herein, other shapes of beverage dispenser and dispenser components are contemplated -
Filter assembly 114 further includesfilter 118,filter base 120, and sealinggasket 122.Filter 118 is typically a removable purification filter unit, such as a composite ceramic/carbon filter, that ensures water, e.g., common tap water, is substantially purified and meets NSF standards.Filter 118 may be commercially obtained from Fairey Industrial Ceramics, Ltd. of England under the tradename DOULTON-IMPERIAL 6″ STERASYL ATC CANDLE. Whenfilter 118 is “spent”, water does not flow through the filter, indicating it is time to replace the filter with a new one.Filter 118 is adapted for fit withfilter base 120.Gasket 122 creates a seal betweenfilter base 120 andnon-chilled reservoir 102 when the filter is screwed intocheck valve 104 to formfilter assembly 114.Gasket 122 provides a tight seal betweenfilter base 120 andfilter 118.Filter assembly 114 may be secured tonon-chilled reservoir 102 by turning threadedstud filter base 120 intonon-chilled reservoir 102. This attachment mechanism provides easy installation and removal offilter assembly 114.Gasket 115 positioned on the neck ofnon-chilled reservoir 102 provides a leak-proof seal whennon-chilled reservoir 102 is joined tochilled reservoir 106. Alternatively, the beverage dispenser of the present invention could be adapted for accommodating other types-of filters; for example, the beverage dispenser could be adopted to accommodate one or more BRITA® or P{overscore (U)}R® type filters. Additionally, while the filter assembly of the present invention is illustrated as being disposed and releasably secured between upper non-chilled reservoir and lower chilled reservoir, the filter assembly of the present invention may be disposed and secured between upper non-chilled reservoir and a connecting or collecting reservoir as described infra. -
Check valve 104 is inserted in a recessed portion of the base ofnon-chilled reservoir 102.Check valve 104 is any conventional check valve or other conventional fluid control assembly.Check valve 104 joinsnon-chilled reservoir 102 in fluid communication withchilled reservoir 106. Whencheck valve 104 is contacted byfilter assembly 114, liquid contained innon-chilled reservoir 102 flows throughcheck valve 104 into chilledreservoir 106 alongpath 124.Non-chilled reservoir 102 andfilter assembly 114 are easily removable for cleaning by simply liftingnon-chilled reservoir 102 out of theouter housing 108. It should be appreciated by those having skill in the art that the present invention may be adapted to comprise more than one filter assembly and more than one corresponding check valves. For example, two, or a plurality of filter assemblies and their associated check valves and components could be disposed in linear relationship with one another or, operatively arranged about a common radius for passing liquid from the upper non-chilled reservoir to the lower chilled reservoir. - Lower chilled
reservoir 106 is designed to receive a quantity of substantially room temperature liquid from uppernon-chilled reservoir 102 and efficiently chill the liquid to a desired drinking temperature. Lowerchilled reservoir 106 includes anouter wall 126,insulator 128,reservoir top 130,inner wall 132, and chilling/heating assembly 134. -
Outer wall 126,reservoir top 130, andinner wall 132 are typically cylindrical in shape and may be formed from injected molded ABS plastic.Outer wall 126 is formed to provide a planar top structure with a relatively narrow opening, which functions to physically supportnon-chilled reservoir 102 and an open bottom structure.Reservoir top 130 is molded to define a relatively narrow cylindrical opening for insertion ofnon-chilled reservoir 102.Inner wall 132 is formed to provide a cylindrical opening for insertion of chilling/heating probe 136 and attachment of chilling/heating assembly 134. -
Reservoir top 130 is attached toinner wall 132 by screws, which fastenreservoir top 130 to lip ofinner wall 132 to provide an enclosed cavity for liquid.Inner wall 132 with attachedreservoir top 130 is inserted inouter wall 126. The cavity formed betweenouter wall 126 andinner wall 132 is substantially filled withinsulator 128, typically thermal expansion polyurethane foam.Insulator 128 provides insulating value to chilledreservoir 106. - Chilling/
heating assembly 134 provides chilling capacity ofchilled reservoir 106. Chilling/heating assembly 134 includes chilling/heating probe 136,semi-conductor disk 138,heat exchanger 140,fan 142,thermal switch 144, and chiller tank-mountingbase 146 and other electronically controlled devices. As shown in FIGS. 7 and 8, the various electrical components of the present invention may be supplied with electrical power and controlled by circuits generally known in the art. - Chilling/
heating probe 136 is provided for cooling liquid in lower chilled reservoir. While a semi-conductor chilling mechanism (Peltier element) is described herein, other chilling units may be utilized for chilling liquid in lower reservoir, for example, a mini-compressor may be used to chill liquid in lower reservoir. The semi-conducting chilling mechanism comprises extruded anodized aluminum for providing increased surface area for enhanced chilling capacity. Chilling/heating probe 136 is inserted inchilled reservoir 106 through a cylindrical opening ininner wall 132. - The cooling capacity of chilling/
heating probe 136 is provided bysemi-conductor disk 138 made from two ceramic substrate plates used to sandwich positive and negative semiconductor pellets of doped bismuth telluride. The semi-conductor disk is placed between chilling/heating probe 136 andheat exchanger 140;heat exchanger 140 is screwed to chiller tank-mountingbase 146.Semiconductor disk 138 is typically a conventional square thermal disk with a cooling side in physical contact with chilling/heating probe 136 and a heat transfer side in physical contact withheat exchanger 140.Semiconductor disk 138 is of a type generally known in the art of electronic cooling and may be commercially obtained from TE Technology, Inc. of Traverse City, Mich. When an electrical current is applied to the semiconductor disk, the semiconductor disk exhibits the Peltier Effect and extracts thermal energy at the cold side, effectively extracting heat from the liquid contained inchilled reservoir 106 via chilling/heating probe 136 and transferring the extracted heat via the hot side toheat exchanger 140. Chilling/heating assembly 134 may operate on any voltage ranging from 9 to 24 volts DC and 110 to 240 volts AC. -
Heat exchanger 140 is any conventional heat sink, such as an extruded aluminum heat sink. At its maximum output,heat exchanger 140 measures approximately 96°F. Heat exchanger 140, which is typically larger in diameter thansemiconductor disk 138, is attached to the bottom of chiller tank-mountingbase 146 by screws and securessemiconductor disk 138 to lower chilledreservoir 106 in contact with chilling/heating probe 136. - The heat transferred from
semiconductor disk 138 toheat exchanger 140 is dissipated to the external environment byfan 142 through heat sink ventilation holes 148 inouter housing 108.Fan 142 is attached toheat exchanger 140 by screws on the outer fins of theheat exchanger 140. - Chilling/
heating assembly 134 is attached to lower chilledreservoir 106 by two screws located at the base ofheat exchanger 140 that fastened directly into the base of the chiller tank-mountingbase 146. Typically, the liquid volume capacity of lowerchilled reservoir 106 is 40 ounces, a volume approximately three and one-half times smaller than the capacity of uppernon-chilled reservoir 102. The smaller volume capacity of lowerchilled reservoir 106 provides rapid chilling of liquid following dispensing. Typically, when lowerchilled reservoir 106 is emptied and refilled with liquid from uppernon-chilled reservoir 102, the chilling time is approximately 4 to 6 minutes. - The temperature of the liquid in lower
chilled reservoir 106 is monitored and regulated bythermal switch 144 that measures the temperature of the liquid and turns the system on when the temperature of the liquid goes above 42 degrees Fahrenheit and shuts the system off when the liquid fall below 38 degrees Fahrenheit. This temperature range can be changed by changing the thermal switch value or by utilizing an adjustable thermal switch. - Upper
non-chilled reservoir 102,check valve 104, and lowerchilled reservoir 106 are encased inouter housing 108.Outer housing 108 is comprised of an insulated resin shell, typically formed from polyurethane that is readily molded into different artistic and decorative forms.Outer housing 108 further includes a plurality of heat sink intake ventilation holes 148 and a pair of exhaust ventilation holes 149. Ventilation holes 148 allow the intake of air to coolheat exchanger 140 andventilation holes 149 function to dissipate heat generated by lowerchilled reservoir 106.Outer housing 108 is attached to lower chilledreservoir 106 byscrews 150.Outer housing 108 provides an insulating value to help keep the liquid insidebeverage dispenser 100 cool to reduce the time required to chill the liquid. -
Spigot 112 extends fromhousing 108 through cylindrical openings inouter wall 126 andinner wall 132 into the bottom of lowerchilled reservoir 106.Spigot 112 provides easy access to the chilled liquid.Spigot 112 is typically any conventional spigot, such as a THOMPSON™ spigot used on typical bottle water coolers. - Liquid contained in upper
non-chilled reservoir 102 is protected from airborne contaminates, such as dust and particulates, bylid 110, which is typically dome-shaped and provides a handle for ease of placing or removinglid 110 from its resting position onouter housing 108. -
Beverage dispenser 100 is a self-contained, compact, portable device that provides chilled liquid on demand. In one example, beverage dispenser 100 (11″ diameter×17¾″ high) readily fits on a counter top. The compact size and portability ofbeverage dispenser 100 are ideally suited to a number of environments, such as use in homes, offices, camps, boats and recreational vehicles (RVs). - In operation, a consumer fills
non-chilled reservoir 102 with a liquid, such as tap water. Gravity feeds tap water throughfilter 118 viacheck valve 104 into lowerchilled reservoir 106. Chilling/heating assembly 134 chills liquid in lowerchilled reservoir 106. The consumer dispenses the chilled liquid fromspigot 112. The withdrawn liquid volume is replenished by liquid from uppernon-chilled reservoir 102, which is rapidly cooled to the desired drinking temperature. - In an alternative embodiment of the present invention, removing
filter 118 allows a liquid in uppernon-chilled reservoir 102 to flow directly thrucheck valve 104 into lowerchilled reservoir 106 to allow other chilled beverages, such as lemonade, tea or KOOL-AID® brand beverage, which do not require purification, to be dispensed on demand. - Referring now to FIGS.3, 5-6 and 9, the present invention may also be adapted for maintaining a beverage at ambient air temperature, for heating and cooling beverages, or for infusing beverages with CO2 gas.
- FIG. 3 illustrates
beverage dispenser 200, which is essentially similar tobeverage dispenser 100, but configured for dispensing beverages at or near ambient air temperature. Hence,beverage dispenser 200 is shown to comprise uppernon-chilled reservoir 102, which is separated from lowernon-chilled reservoir 105 by means offilter assembly 114. - Alternatively, FIG. 5 illustrates that the present invention may be configured to comprise beverage dispenser300, which is also essentially similar to
beverage dispenser 100, but which is configured for dispensing cooled beverages and beverages maintained at ambient air temperatures. In this embodiment, it is seen that beverage dispenser 300 comprises non-chilled connectingreservoir 302, which is disposed between uppernon-chilled reservoir 102 and lowerchilled reservoir 106. Because the rate of flow of highly efficient filters tends to be slow, non-chilled connectingreservoir 302 is provided to increase the rate at which the lower reservoirs (heated, cooled or ambient air temperature reservoirs) may be filled when liquids are dispensed.Filter assembly 114 is provided for passing liquid from uppernon-chilled reservoir 102 to non-chilled connectingreservoir 302. Non-chilled connectingreservoir 302 is operatively arranged to pass filtered liquid, which liquid is maintained at ambient air temperature, to spigot 304 or to lower chilledreservoir 106, which is adapted to chill beverages by means of a semi-conducting cooling element or other appropriate cooling means, for example, a mini-compressor. Chilled beverages may be dispensed by means ofspigot 112. It should be appreciated, however, that while the various embodiments disclosed herein are shown as comprising one or more individual spigots for dispensing various beverages (heated, cooled, ambient, and CO2 infused as described infra) the present invention may be configured to comprise a single spigot and associated valve and switching mechanisms (mechanical or electromechanical) for dispensing the various beverages on demand. - In FIG. 6 it is seen that the beverage dispenser of the present invention may be configured for dispensing beverages that are chilled or heated. In this
embodiment beverage dispenser 400 is configured to comprise uppernon-chilled reservoir 102, non-chilled connectingreservoir 302, lowerchilled reservoir 106 and lowerheated reservoir 304.Filter assembly 114 is configured to pass liquid from uppernon-chilled reservoir 102 into non-chilled connectingreservoir 302. Non-chilled connectingreservoir 302 is operatively arranged to pass filtered liquid, which liquid is maintained at ambient air temperature, to lower chilledreservoir 106 and to lowerheated reservoir 304. Lowerchilled reservoir 106 may be chilled by means of a semi-conducting cooling element or other appropriate cooling means, e.g., a mini-compressor, and lowerheated reservoir 304 may be heated by a semi-conducting element, heating coil, or by means of heat emanating fromheat exchanger 140.Beverage dispenser 400 may also be adapted to dispense beverages at ambient air temperature if desired. It should be appreciated thatcheck valves 104, or other appropriate means may be disposed between the connecting reservoir and the lower reservoirs to prevent mixing of the heated and cooled liquids. The lower heated and chilled reservoirs may be insulated from one another by means of appropriate insulative materials. - Finally, FIG. 9 illustrates that one or more embodiments of the present invention may be configured to comprise a CO2 charging unit for infusing a liquid with CO2 such that effervescent beverages may be dispensed. In this figure, it is seen that
beverage dispenser 500 comprises uppernon-chilled reservoir 102, non-chilled connectingreservoir 302, lower CO2 reservoir 502, and CO2 cartridge 503. CO2 cartridge 503 may be similar to that typically utilized for soda and tonic water dispensers and may be rotatably secured and sealed to the CO2 reservoir. To prevent beverages infused with CO2 and contained within the CO2 reservoir from becoming “flat”, CO2 reservoir comprises a check valve for preventing CO2 gas from passing to the connecting reservoir. This embodiment further illustrates that the beverage dispenser of the present invention may be configured to comprise more than one releasable filter assembly. It should be appreciated thatbeverage dispenser 500 may also be further adapted to dispense non-carbonated beverages, and/or beverages that are heated and cooled.
